Even stranger things
Of the many bizarre stories of what happened at Camp Hero, Stranger Things only uses three of the core elements: portals, the monster, and children with psychic powers. But looking forward to Stranger Things Season 2 (which has not yet been officially green-lit by Netflix), the ongoing rumors of government misconduct at Montauk provide many creepy options for how the story of the boys, Eleven, and Doctor Brenner works out. Some testimonials from Montauk survivors make mention of alien lifeforms, either of the classic gray-skinned variety or something weirder, like giant lizard people or extra-dimensional beings that appear in a humanoid shape made of hollow glass. The time-travel element is also in play, and connections back to the "Philadelphia Experiment," the conspiracy theory that gave rise to all the Montauk stories.
The bulk of the Montauk Project is set around the same time as Stranger Things, but true believers like Nichols and Bielek, up until he passed away in 2011, maintain that these experiments dealing with the expansion of human consciousness and future technology are still going on somewhere, somehow. In 2008, an unidentified carcass of an animal washed up on the beach of Long Island, adopting the label of the "Montauk Monster" from the early 1990s version (Cameron's creation is commonly referred to as "Junior" now). Urban explorers still venture into Camp Hero on Long Island, where some claim you can still hear screams in the abandoned tunnels. Sporadic reports that the closed base still draws military-levels of power despite being "inactive" persist, and the truth about Camp Hero and what happened there continues to be concealed beneath multiple layers of rumor, myth, and the "fiction" of Stranger Things.
